The ICS Triplex T8110B is the central TMR processor for Trusted safety systems. It provides triple-redundant logic execution, deterministic performance, and SIL 3 reliability for critical emergency shutdown and fire and gas applications.
The ICS Triplex T8110B serves as the primary Central Processing Unit (CPU) for the Trusted™ Triple Modular Redundancy (TMR) safety system. This module is the core intelligence of the architecture, executing the safety logic and managing all I/O subsystem communications. Consequently, the T8110B utilizes a specialized triple-processor design where three independent execution engines perform identical calculations and vote on the results. This 3-2-0 voting mechanism ensures that a hardware failure in any single processor branch is detected and masked, allowing the process to continue without interruption.
Furthermore, the T8110B is designed for high-speed, deterministic logic execution, which is critical for complex Emergency Shutdown (ESD) and Fire and Gas (F&G) applications. Because the module incorporates dedicated system and communication co-processors, it can manage heavy network traffic and diagnostic routines without degrading the scan time of the safety-critical application. Additionally, the processor features extensive non-volatile memory for application storage. Therefore, the system retains its configuration and safety logic even after a complete power loss.
Moreover, the T8110B provides a wide array of communication interfaces for integration with external Distributed Control Systems (DCS) and Human Machine Interfaces (HMI). Due to its integrated health monitoring, the processor provides detailed internal status data, enabling proactive maintenance strategies. By utilizing the T8110B, industrial facilities can achieve the highest levels of safety and availability, fully complying with international SIL 3 standards while minimizing the risk of nuisance trips.
